Description

Technical Field

[0001] The utility model belongs to the technical field of constant pressure variable frequency water supply, in particular to a constant pressure variable frequency water supply device for ships. Background Art

[0002] Constant pressure water supply is a water supply method of water conservancy system. Water supply is an indispensable and important part of national production and life. The traditional water supply method occupies a large area, the water quality is easily polluted, and the infrastructure investment is large. The main disadvantage is that the water pressure cannot be kept constant, resulting in some equipment not working properly. Constant pressure water supply can keep the water supply pressure constant, and can keep the balance between water supply and water use, that is, when water is used more, the water supply is also more, and when water is used less, the water supply is also less, thereby improving the quality of water supply. When the ship uses the constant pressure variable frequency water supply device, the water source needs to be injected into the water tank.

[0003] The existing constant pressure variable frequency water supply device for ships is in use. Since the water source needs to be stored in the water tank for a long time, a large amount of impurities such as scale will adhere to the inner wall of the water tank, resulting in a decrease in water quality. In view of this, we propose a constant pressure variable frequency water supply device for ships. Utility Model Content

[0043] In this embodiment, the water source in the water inlet pipe 11 is filtered by the filter screen 19 in the filter frame 15. After the filter screen 19 has been used for a long time, it is necessary to replace the filter screen 19. The staff rotates the working screw 16, and the rotation of the working screw 16 drives the connecting plate 18 to slide along the inner wall of the filter frame 15 through the threaded slider 17.
